So ive noticed this with many leos and wonder why they do this. Our leo sits in her hide against a near wall and closes the eye closest to the wall and leaves the other eye open facing the rest of her tank. My logic tells me that she does this as protection in order to keep an eye on her surroundings while resting. She only seems to do it when her head is out of the hide. I have seen this with many leos so i know im not alone in this behavior. Any thoughts?
